Is the benefit of using a language server as opposed to just giving access to the codebase simply a reduction in the amount of tokens used? Or are there other b

  Yes. It lets the LLM immediately obtain precise information rather than having to reason across the entire source code of the code base (which ChatDBG also enables). For example (from the paper, Section 4.6): The second command, `definition`, prints the location and source code for the definition corresponding to the first occurrence of a symbol on a given line of code. For example, `definition polymorph.c:118` target prints the location and source for the declaration of target corresponding to its use on that line. The definition implementation leverages the `clangd` language server, which supports source code queries via JSON-RPC and Microsoft’s Language Server Protocol.

  Beyond saving tokens, this greatly improved the quality and speed of answers: the language server (most notably used to find the declaration/definition of an identifier) gives the LLM 1. a shorter path to relevant information by querying for specific variables or functions rather than longer investigation of source code. LLMs are typically trained/instructed to keep their answers within a range of tokens, so keeping shorter conversations when possible extends the search space the LLM will be "willing" to explore before outputting a final answer. 2. a good starting point in some cases by immediately inspecting suspicious variables or function calls. In my experience this happens a lot in our Python implementation, where the first function calls are typically `info` calls to gather background on the variables and functions in frame.
